FUNCTIONING

• The stale air drawn in by the hood passes through high-efficiency shock filters and then through 2 UV lamps placed across the tappings in the extraction sensor.
• Under the action of UV-C rays, the molecules are modified according to two combined effects, photolysis and ozonolysis, with the result of reducing grease deposits and neutralizing odors.

Photolysis effect

• UV radiation in the wavelength 185 nm and 254 nm breaks down long-chain molecules (fat molecules, etc.) by direct photolysis; the various chemical bonds are broken by the UV photons.

Ozonolysis effect

• UV photons react with oxygen in the air and create ozone (O3), which breaks down into active oxygen. Both compounds have a long-lasting oxidizing effect on molecules, removing grease and odors.

• Triple safety device to prevent direct exposure to UV radiation of people present in the environment of the lamps:

1. 1. Position contact at the filters via a safety plate: when a filter is removed, operation of the lamps is not permitted.
   2. Use of specific impact filters compliant with NF EN 16282-6 equipped with a covering profile to fill the space between 2 filters and reduce radiation.
   3. Safety pressure switch inside the sensor of each hood: if the pressure (extraction flow) is insufficient, the operation of the lamps is not authorized. The safety pressure switch authorizes the switching on of the lamps above a pressure of 25 Pa (530 m³/h/ml of hood) in the extraction sensor and cuts off the lamps below 13 Pa (330 m³/h/ml).

• Provide a waterproof network and ensure the waterproofing at the connection to the fan.
• Respect the regulatory distance of 8 meters between the stale air outlet and any fresh air inlet or opening.
• Discharge stale air into a free and naturally ventilated outdoor space/volume.
• Provide post-ventilation to avoid any possible unpleasant residual odor but not harmful to health.
• For better efficiency in the extraction network, the stale air must be in contact with the ozone for at least 2 seconds before discharge. If the speed in the duct is 3 m/s, the minimum length must be 6 m. L minimum duct [m] = 2 x V sheath [m/s].
• In the event that the implementation of sufficient sheath length is not feasible or in the event that the residual odor of ozone upon discharge would be bothersome
• for the neighborhood, it is advisable to trap the ozone via a KPCA activated carbon box installed as close as possible to the stale air discharge.
